Prerequisites
To configure SAML SSO, you need an active CoreWeave account and admin permissions.Configure SAML SSO for your organization
This section explains how to set up SAML single sign-on (SSO) for your organization so members can authenticate through your identity provider (IdP) instead of CoreWeave credentials. You can configure SAML SSO policies for CoreWeave Kubernetes Service (CKS) manually or with a metadata URL. Choose the method that matches what your IdP exposes.- Configure manually
- Configure with metadata
Configure SSO manually
Use the manual configuration when your IdP doesn’t publish a metadata URL or when you prefer to enter each value yourself. Before you configure the SSO policy manually, gather the following information from your identity provider (IdP):- The IdP’s SSO URL.
- The IdP’s unique Entity ID.
- An X.509 security certificate provided by your IdP.
- In Cloud Console, go to SAML SSO configuration and click the Configure SAML button.
- Select the Manual Configuration tab:

- Enter the SSO URL, the Entity ID, and the provided X.509 security certificate.
- If your IdP signs the SAML assertion, expand Advanced settings and select Require signed assertion.
- Click the Next button.
- Confirm the information in the dialog boxes is correct.
- Click the Deploy SSO button to activate the policy.
Add attributes to the IdP
CoreWeave uses these attributes to identify each user who signs in through SSO. After you deploy the SSO policy, add the following attributes to your IdP:
While in your IdP settings, also verify that response signing is enabled. The SAML response must be signed. Authentication fails if the response is unsigned.
Manage the SSO policy
After the initial setup, you can return to the SAML SSO configuration page to review or change the policy. The configuration dialog displays the policy’s information and lets you manage it with the following buttons: Disable SAML, Enable SAML, and Edit.Access the SSO login page
After you configure SSO for your organization, direct users to sign in with your organization’s dedicated SSO login URL. The SSO login URL follows a standard format that includes your organization’s unique ID directly before the final/login path segment.
To access the SSO login URL:
- In Cloud Console, go to Account Settings and find your CoreWeave Org ID.
-
Replace
[ORG-ID]in the following example with your Org ID.Example If your Org ID isabc123, your SSO login URL is: - Share this URL with your team so they can sign in with your SSO configuration.
